I made the world's smallest example, taken from the CMake tutorial.
There's a CMakeLists.txt that contains this:
cmake_minimum_required (VERSION 2.6)
and a tutorial.cxx that contains this:
// A simple program that computes the square root of a number
int main (int argc, char *argv)
if (argc < 2)
fprintf(stdout,"Usage: %s number\n",argv);
double inputValue = atof(argv);
double outputValue = sqrt(inputValue);
fprintf(stdout,"The square root of %g is %g\n",
Just create the two files above and do:
$ cmake .
$ ./Tutorial 2
On 32-bit Cygwin, it all works nicely as expected. But on my fresh 64-bit
installation, I get the " not able to compile a simple test program" message.
I think Hans-Bernhard's theory that there's some other app interfering is
probably correct, and it probably has something to do with my company's
I will post more information in subsequent posts that hopefully stay under
the "spam score threshold".
